Molten material applicator



y 1965 R. N. BAEHR ETAL MOLTEN MATERIAL APPLICATOR Filed June 10, 1963 United States Patent 3,195,794 MOLTEN MATERIAL APPLICATDR Robert N. Baehr, 136 Neptune Ave., New Rochelle, N.Y.,

This application is a continuation-in-part of applicants copending application Serial No. 143,264 filed August 28, 1961, now abandoned.

The present invention relates to a tool for the application of molten material, such as solder, in such a manner that it can be dripped on to the point of application.

An object of the present invention is the provision of a means for application of such materials with one hand instead of the present method requiring one hand to hold the material and the other to apply the heating device.

Another object of the present invention is the provision of a means of application of such materials with greater precision and speed than is possible with present methods.

The objects of the present invention will become more apparent upon reading the following specification and referring to the drawing in which the essential parts are designated by numerals.

FIGURE 1 is a vertical sectional view of the cannula attached to the partial ring.

FIGURE 2 is a vertical sectional view of a soldering iron constructed in accordance with the invention.

FIGURE 3 is a transverse sectional view of the partial ring which constitutes the fundamental feature of the invention.

The invention consists of a heating tip 3 encircled by a partial ring 2 on to which and from which is attachable and detachable a cannula 1 into which the heating tip extends when the cannula is attached and which is graduated at one end thereof to a perforation. It may be made out of metal, ceramic material or any material suitable for its purpose.

The tool will be used as follows: the material to be melted and applied will be inserted in the cannula between the exterior surface of the heating tip and the interior surface of the cannula; when the material is melted 3,195,794 Patented July 20, 1965 by the heating tip it will be dripped through the perforation therein on to the point of application.

While we have illustrated and described the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims:

Having thus described our invention, what we claim as new, and desire to secure by United States Letters Patent 1s:

1. A tool for application of molten material, such as solder, comprising a heating tip, the base of which is partially encircled by a partial ring on to which is attached a detachable cannula into which the heating tip extends and which is graduated at one end thereof to a perforation, whereby material inserted through the open area between the ends of the partial ring and into the cannula between the exterior surface of the heating tip and the interior surface of the cannula may be melted and dripped through the aforesaid perforation on to a-selected point of application.

2. A cannula graduated to a perforation at one end thereof and at the other end thereof encircling a partial ring which is detachable from and attachable to the base of a heating tip so that the heating tip extends into the cannula, whereby material inserted through the open area between the ends of the partial ring and into the cannula between the exterior surface of the heating tip and the interior surface of the cannula may be melted and dripped through the aforesaid perforation on to a selected point of application.
